I’m not sure where you live or the economics to speak on that but it’s 12+ years old from an era of amd hardware has iffy at best. It’s not something I’d recommend to use a rolling release distro on. Or even something graphically intensive as gnome or KDE. You don’t have to trash it but I think you should temper your expectations and use something thats still x11 maybe an LTS Ubuntu release
AMD bought ATI like 15 years ago so its a vit dated to even mention ATI. For Linux AMD Has overall better GPU drivers especially if you wanna stick to open source drivers tho
